was the titular governor of north Arakan during the reign of his father King Kyansittha of the Pagan Dynasty of Myanmar (Burma).

The stone inscription has scholarly significance because it allowed the deciphering of the Pyu language.

At Pagan, Kyansittha was sent into exile again—this time to Dala (modern Yangon) for renewing his affair with Manisanda.

A remorseful Kyansittha made Yazakumar the titular head of north Arakan and seven hill districts.

The inscription dated 1113 was written in four languages: Pyu, Burmese, Mon, and Pali, which all tell the story of Yazakumar and his father Kyansittha.
